TO ALL WHOM .IT MAY Y CONCERNQ Be itlcn'own that I, L. C. RODIER, ot' $pring'field, in the county of Hampden, and Commonwealth of Massa# chusetts, have invented anew and useful Improvement in Stezim or-WaterVztlvcs; and I do horehy declnre'th'at making part o i this specification, und to the'letters oi reference marked thereon, in AWhich` Figure'l is n sideA eievatiomof one modilicntion voi' my invention, or of n. shell, with zr'plug oud-hinge-valve inserted. v I i Figure 2 is un endviewof the same.'

Figure 11 islxm eudview ofthe seme; end Figure' 12 is. a longitudinatl'lvertieal section of "the valve-shell and 'connectingpipes through line G H of iig. 3. The vnature of my invention consists in' the construction and A"errengement;-of e water or steam-valve, in which the valve iss-placed `in n plug-which is tnpered,loris in the form of vnftruutzaivted eoue, snid plugbeng 'inserted in the valve-shell ola. globe-'valvQwliich is4 so constructed' as to-.admitoffthe insertion of different plugs huviug'diiferent kinds of vulves therein, sotliat the shell and valve may heusei'astx heck-valve or a.

throttle-valve without disturbing the piping or 'valvefshell in .the operntiouof changing one valve for `another. .Y

As ordinary steam nndwnter-valves are constructed, it' is n matteiof considerable labor-und expense, to say nothing ofivexstious'delnys, I'vhen out of repair, toremove thevnlvefor vthe purpose of repairing it,rasiit is necessary to remove the whole shell from the pipes.- l

By my invention, when any foreign substance should get between the valve and its sent, or from n'uy other conse the valve should refuse to oct, I am enabled quickly and easily to withdraw the plug by u. slight hlowupon its smaller end, remove the obstruction, andinsert theplug in'its'placein the shell. If from puy cause'itmay l J h'emdesirahle to remove a. check-valve, undf use, instead, thrttlevalve, I simply remove the check-vlve plug andinsert in its place a. throttle-vulve plug, which is 'a matter of little or no trouble, while in other va-lvssuch a change is a matter'of much diliculty, and attended withV more or less labor and expense; y

That others skilled-in Athc nrt may he able to vmake and Ause my invention, I will' proceed to" describe itsconstruetion andoperation.

In the drawings, A represents the valve-shell, which may besphericslin i'orrn, and to which are Ijoined theA cunnecting-pipes ZI b, the 'scid shell having a'perforation, B, whioh'isonical'for in the'form' of atruucntedcone,

andl so madethot the plug, when.` inserted inV its place in said perforated shell, shall it it closely. is o, plug, made Aoi'such form ns to t the perforation B in the valve-shell A, and'havng the smi-cy1indrical space a upon one side, :md the port 1or orifice d leading from the said-space ato the opposite side of the plug. I Upon one side'of this space a,`a.ncl at each end thereof, is the 'recess c', into which is insertedthe liigc c'of the valve the face lc of the said valve being made dat to fit-its seat kin the plug 4Ah The orifice d may be of any desired form, as may be moet adapted tol the'free and direct passage'of Iwnter or steam through it, and the ends :c of the plug 1 may he spherical in form to 4conform to the shape of .the vaise-shell A( I also make, to it the same perforation B inthe valveshell A, another plug, A2, hving a vnlve-chamhei, y

c, therein, oneA sideft, of said velve-chember beingmade upon enplnue-palrollelto thehis of the'valve-slzem l, and forming' n seat 'for the valve It, while the opposite side a of the valve-chamber s .is made upon s. plane, which,

as it extends d ownwardfrom its upper part, inclines toward the exis of'th'e valve-stemt, or the position of seid i plane s is at an angle to thoperpendioular position of the valve-stem Lflathe upper partei.. thelvalve-plugAis the socket e', at tlf-.e lowerpart of which is the bevelled shoulder i, and from thence to the-valve-chamlier a is a perforation t'o admit .the insu tion of the valve-stem Z. A male screw thread is cnt npon' 'the lower portion of .this valve-stein l, and ata little distance ahovc this thread is the collar i', which is bevclledupon its'lwer side to lit the bevelled shoulder z', and is also bevelled upon its upper .sidelto lit the hevelled portion in the lower 'end of the packing-nut -gY The lower portion g of the packing-nut g is of a. size to {it the socket e,'and should'inpr'actice haven. tuale-'screw thread cut thereon to engage withn.

femaleLscr-ew thread cntin the socket :eff 'The packing-nnt'ghas a cylindrical perforation, into andthrough which is passed the valve-sttn Z, to the'upperen'dof whichis pr'operlysecured the' hand-wheel w. A'lhe vulve h has a vertical cylindrical perforatiom'o, in which'is cut a. feinalefscrewl thread, which engages. with'the screwthread cut upon the valve-stem 1, and the face e ot'r'thevalve h iis madeupon a plane parallel to the axis of the valve-steml, and also parallel to the plane'of the'ivalve-seat t. -The oppositev orback sidey uzelf thel valve is made upon a. plane parallel to the' planeet' the side s of the valve7chamher. s, and said valve h is of proper wiglthand heightto perfectly cover or close the'prt 1; uhcn the nid-valve lr is at the lower part of the chamber s, and in a proper position to cover or close-'said port p, and the ports ni'and p may he ci' any desirahle shape which may he adapted to the free passage -of water or steam entirely through the' plug v .The operation of the vulve is es fol-lotvst'vfllhe hinge c of the valve a is inserted in its socket c inthe-.plug Al, and theplug Al is theninserted in its socket.v B in the shell A. The valvel is then ready for use as a checlt-4 valve., The water or steam being-admitted through' the aperture d, in thedirection indicated bythe arrow, forceethe'valve a open in aposition shown in g. 5, and any reactionary movement of thervatcijor steam, which causes'V pressure backward toward the aperture d, after passing thevalve a', forces the valve a against its seat lc`- or close-s it, thus preventing any passage of the water or steam hack-ward past'l the valve a and through the apertured.' In large check-valves fit may be necessary to'insert two or more smaller valves in place of a single large one, so as 'to lessen the noise of the valves, and divide-the strain, and4 to. make a correspondingnumher of ;valveflsents. If 4it should'he desirable to use a throttle-valve instead-of acheck-val've, though in the saine place',

ahloxv upon thesmaller end of the plug Af removes it from the shell A. i The valve it is inserted in the valve-chamber n, the valve'stem passeddown through thenperture leading to l thevalve-chamber s, and screwed into theaperture in the valve 7t, the-u'pper end of the valve-stein Z beingpassed through the perforationin the packing-nut g, and the'paclring-nut is then" screwed into thc socket' e, and the hand-wheel w attached and properly secnyedto the upper `end of the'vlvetet'n l. The plug is,then inser ted into. the-same perforation B in the shell A. If the' valve is closed, and it is desired to-openit, the valve-stem is turned into fthe valve k hy means of the handwheela until the valveh is raised, so that' the wateror .steanij isadmitted into the 'port m, passes under the valve h, and out ofthe port p'. As the valve h descends in closing,`

when nearly closed, the side upf theivalve h comes in contact with the side s of Vthe valve-cliauller s, which;A

,being inclined to the plane of the valve-seat t, and also yto the axis of the valve-stem l, forces'orpresses the valve' hdirmly against its 'seat t. The pressure of the water,'nlso, through lthe 'port nl., againstA 4the valve 'assists in keeping the said valve lirnily to its seat'.A f i ,i

As my invention does not u consist in. the particular kind. of valve used in the plug, luft consists 'in-c.

'removable plug (containing a valve or valves, and a seetforscats, and) inserted in the valve-'case or shell,- thus constituting an entire steam or water-valve, the plug may be fitted with any desired kind of' valve, which can` he operated in the conical plug l'lhe `perforation or seat B' in the shell or `caseA might he cylindrical, instead oi' tapering, and the plug might also he rnade cylindrical to fit the said cylindrical seat in lthe shell orA case'A, in which case the plug could .be secured in yits seat B by means of screws or pins.- A -female-screwthread 'might-also becut in this seat B, and a screw-thread cut upon the plug, and the plug be turned into place in itsseat; but I prefer-the method as shownin the drawings, 'as being cheap'and convenient.

Having. described my invention,.what I claim as new, and desire to secure hyLett'egs Patent, is... Themetallic plug, having oneor more valve-seats` therein, and one or more valve attached thereto, in

combination with the shell or case Aof e globo-valve, the aperture B being constructed therein so as 5to receive said ping, and the whole arranged substantially as herein described and s`etforth.
